The Holy Eucharist is the most important of the seven sacraments because, in this and in no other sacrament, we receive the very body and blood, soul and divinity of Jesus Christ. Innumerable, precious graces come to us through the reception of Holy Communion.

Communion is an intimate encounter with Christ, in which we sacramentally receive Christ into our bodies, that we may be more completely assimilated into his. "The Eucharist builds the Church," as Pope John Paul II said (Redemptor Hominis 20). It deepens unity with the Church, more fully assimilating us into Christ (1 Cor. 12:13; CCC 1396).

The Eucharist also strengthens the individual because in it Jesus himself, the Word made flesh, forgives our venial sins and gives us the strength to resist mortal sin. It is also the very channel of eternal life: Jesus himself.

Because of the gravity of Jesus’ teaching on receiving the Eucharist, the Church encourages Catholics to receive frequent Communion, even daily Communion if possible, and mandates reception of the Eucharist at least once a year during the Easter season. Before going to Communion, however, there are several things one needs to know.

This tract outlines the Church's requirements for reception of Communion.
